2015Summary:
The aim of this project is to study the short term and long term effects of different fire intensities on the decomposition of soil organic matter (SOM) in northern boreal forests under changing fire regimes.
The objectives are to: 1) explore the short and long term effects of forest fires with different intensity on above- and belowground biomasses; 2) explore changes in albedo, snow depths an...

Summary:
The objectives of this project are to:
1) create a series of maps showing the thaw slump activity along the Beaufort Sea Coast near Tuktoyaktuk;
2) develop detailed water, vegetation, and ground temperature maps of the study sites using drones;
3) examine the effects of thaw slumping on the water quality of landscape-level runoff to the Beaufort Sea;
4) examine the effects of coastal erosion ...

Summary:
The proposed project will build on the proven methodology used during previous permafrost studies in Jean Marie River First Nation (JMRFN). It aims to extend the vulnerability map by including the McGill and Deep Lake area. These lakes are traditionally and culturally very important to JMRFN (for example, the area surrounding these lakes is also used repeatedly by caribou year after year) and the ...

Summary:
The objectives of this project are to test if passive seismics can be used to map the thickness of overburden in a permafrost-rich environment; and, to compare overburden thickness derived from passive seismic data and known overburden thickness from drilling.
This project will test to see if the earth’s natural vibration can be used to determine how much sand, gravel, soil and permafrost are a...

Summary:
The goal of this study is to understand landscape response following ice-rich terrain alteration.
The research team will install temperature loggers in 2" PVC pipe from the surface down to 3 m depth to monitor the ground temperature evolution over the summer season in the pits. The team will also use the geophysical technique electrical resistivity tomography (ERT) to measure the amount and st...

Summary:
After 10 years of warming climate conditions, the Canadian Fire Service is leading a field project to re-measure a series of permanent monitoring plots to identify any changes to the forest stand structure, tree growth rates, plant community composition, tree, shrub, herb, and lichen biomass. These changes will be associated with climate trends and environmental factors such as soil type, presence...

2017201620152014Summary:
The objective of this study is to understand how permafrost slumping increases the mobilization of carbon from land to water, and the effects of this transport on stream communities and the global carbon cycle. This summer, the research team will measure streamwater chemistry upstream and downstream of slump sites. The team will also examine the fate of this carbon by undertaking incubation experi...

Summary:
The objective of this research is to identify impacts of climate change and permafrost thaw on pond methane emissions, and on water chemistry in streams that drain peatland-rich catchments. Impacts on methane emissions will be assessed.
Specific objectives are: 1) to characterize the trends and variability in magnitude of methane emission from ponds along climate gradients within both the Taiga...
